The pygmy rattlesnake is a small, venomous snake that lives in the southeastern United States. It is the smallest rattlesnake found on the North American continent. Its venom is strongly tissue-damaging, but the snake makes so little that a bite is unlikely to be fatal to an adult.1

Početna

It lives in flatwoods, sandhills, longleaf pine savannahs, mixed scrub oak forests and floodplains, and is also found near lakes and marshes. It does not dig its own burrows. It uses holes dug by small rodents or gopher tortoises, and it prefers densely vegetated areas for cover.1

Što jede?

It eats small mammals, birds, lizards, insects, frogs and other snakes, and also giant desert centipedes. Young snakes lure skinks by waving the tail, while adults wait motionless in a coil for days at a time.1

Kako ga prepoznati

Small but bulky in width, usually 40 to 60 cm long including the tail1
Dorsal pattern of oval or roughly circular spots with somewhat regular edges1
Flank spots are mostly round and not much taller than they are wide1
Usually 23 rows of dorsal scales at midbody1
Young snakes may be paler or more vividly marked, and have a yellow tail tip. The rattle is tiny and gives only a faint buzz that is heard from a few feet away1

Otrovna snaga

Ugrizi

Otrov izlazi kroz očnjake ili zube kad ugrize.

Što radi njegov otrov kad ugrize ili ubode?

Its venom is cytotoxic, which means it damages cells, and it is strongly haemorrhagic, which means it causes bleeding. The venom is tissue-toxic but contains no neurotoxins, which attack the nerves. The snake produces only a small amount of venom and contains substantial amounts of serotonin and related compounds.1

Koliko je opasno za ljude?

Opasnost za ljude: BolnoMože jako boljeti, ali gotovo nikad nije ozbiljno.

The snake produces too little venom to be likely to deliver a fatal bite to a human adult.1

Što radi kad se uplaši?

Some individuals are very aggressive and strike furiously, while others are lethargic and do not rattle at all, and many are reluctant to bite.1

Ako ugrize

Neka osoba miruje i bude smirena, drži ugriženi ud u visini srca, skini prstenje i sve što steže i brzo je odvedi u bolnicu.

Ostani na sigurnom

Nikad ne diraj, ne hvataj i ne zadirkuj divlju životinju, čak ni malu, i čak ni ako izgleda kao da spava ili je mrtva.
Ostavi joj prostora. Ako je sretneš, ne paniči, polako se odmakni i pusti je da ode svojim putem.
Ako te neka ugrize: ne paniči, miruj, nazovi broj za hitne slučajeve (112, 000, 911) ili brzo idi u bolnicu. Zapamti kako je izgledala, fotografija pomaže.

Ne želi ti ništa loše. Otrov koristi za lov hrane ili za obranu i mnogo bi se radije sakrilo. Više o sigurnosti

Činjenice

Its venom was the basis for the drug eptifibatide, which is used to prevent clotting during a heart attack.1

It is the smallest rattlesnake found on the North American continent.1

Its rattle is unusually small, which may show the early stages of how rattles evolved.1

Snake fungal disease has risen sharply in pygmy rattlesnakes over the past decade and is a major cause of death, though some snakes have recovered in the field.1

Females may give birth to live young even while infected with snake fungal disease.1
